That Blue Square Thing

AQA Computer Science GCSE

July 2019: the AQA CompSci area is almost complete. Most of the content for units 3-6 is now up and there's quite a lot of Unit 7 material. There's still some work to do, particularly on Paper 1 units, but it's getting there.

Programming Concepts - Mathematical Operators

Basic mathematical operators are addition (+), subtraction (-), multiplication (*) and division (/). BIDMAS rules apply when you're using these, so take care, especially when dealing with multiplication and division.
